Claim
1. An apparatus, comprising:', 'a rotor shaft for a wind power plant to carry at least one rotor blade of the wind power plant;', 'a coupling device; and', 'a gear shaft running coaxially to the rotor shaft, wherein the coupling device couples the rotor shaft to the gear shaft characterized in that the coupling device has a first connection element that can be detachably affixed on the rotor shaft to a first attachment element designed to create a positive locking connection and a friction-fit connection between the gear shaft and the rotor shaft.
2. The apparatus of claim 1, wherein the coupling device further comprises:', 'a second connection element affixed to the gear shaft to create a positive locking connection.
3. The apparatus of claim 1, wherein the coupling device further comprises:', 'a coupling element passed through the first attachment element to produce a friction-fit connection between the rotor shaft and the gear shaft.
4. The apparatus of claim 1, wherein the first connection element has a flange that is essentially rotationally symmetric and is attached to the end face of the rotor shaft which becomes flush at its end that faces the gear shaft, and that the flange has a larger diameter than the rotor shaft.
5. The apparatus of claim 1, wherein the first attachment element is a clamping sleeve that passes through the first connection element and is inserted into the rotor shaft.
6. The apparatus of claim 2, wherein the coupling device further comprises:', 'a clamping sleeve that passes through the second connection element and is inserted in the gear shaft to produce a friction-fit connection between the rotor shaft and the gear shaft.
7. The apparatus of claim 5, wherein the first attachment element is inserted into the rotor shaft and runs coaxially to a clamping sleeve that is inserted into the gear shaft.
8. The apparatus of claim 3, wherein the coupling element is a coupling bolt with a bolt axis running approximately parallel to the longitudinal axis of the rotor shaft.
9. The apparatus of claim 1, wherein the coupling device further comprises:', 'a coupling element passed through the first connection element
10. The apparatus of claim 9, wherein the coupling device further comprises: a plurality of coupling elements including the first connection element preferably arranged at equal distances one behind the other in the circumferential direction of the rotor shaft
11. The apparatus of claim 1, wherein the first connection element is made of a weaker material that can be more easily deformed than the rotor shaft
12. The apparatus of claim 1, wherein the coupling device further comprises: a stopper arrangement for stopping the rotor shaft
13. The apparatus of claim 12, wherein the stopper arrangement has at least one stopper element for stopping the rotor shaft in at least one prespecified rotational position
14. The apparatus of claim 13, wherein the at least one stopper element has a stopper opening facing radially outwards relative to the rotor shaft
15. The apparatus of claim 12, wherein the stopper arrangement has a stopper ring that surrounds the first connection element and is preferably affixed to the connection element
16. The apparatus of claim 15, wherein the stopper ring has a plurality of stopper elements with stopper openings that are arranged one behind the other in the circumferential direction
18. An apparatus, comprising:', 'a rotor shaft for a wind power plant to carry at least one rotor blade of the wind power plant;', 'a coupling device; and', 'a gear shaft running coaxially to the rotor shaft, wherein the coupling device couples the rotor shaft to the gear shaft characterized in that the coupling device has a flange with coupling bolts that can be detachably affixed on the rotor shaft to create a positive locking connection between the gear shaft and the rotor shaft and a clamping sleeve to create a friction-fit connection between the gear shaft and the rotor shaft, wherein the flange is made of a weaker material that can be more easily deformed than the rotor shaft
19. The apparatus of claim 2, wherein the coupling device further comprises:', 'a coupling element passed through the first attachment element to produce a friction-fit connection between the rotor shaft and the gear shaft.
20. The apparatus of claim 19, wherein the coupling element is a coupling bolt with a bolt axis running approximately parallel to the longitudinal axis of the rotor shaft.']
