A wind turbine (101) comprising a torque transmitting coupling (1) between a first rotatable part (2, 3) and a second rotatable part (2, 3) of the wind turbine (101), e.g. in the form of a hub (2) and a shaft (3), is disclosed. The torque transmitting coupling (1) comprises a form- fitted coupling and a compression means (5, 8, 9, 12, 13). The form-fitted coupling defines a plurality of drive flanks formed on the first rotatable part (2, 3) and a plurality of driven flanks formed on the second rotatable part (2, 3). The compression means (5, 8, 9, 12, 13) is arranged on an internal or external perimeter of the form-fitted coupling, and the compression means (5, 8, 9, 12, 13) provides a frictional coupling between the first rotatable part (2, 3) and the second rotatable part (2, 3). The torque transmitting coupling (1) is capable of locking up to six degrees of freedom between the first rotatable part (2, 3) and the second rotatable part (2, 3), while allowing the first rotatable part (2, 3) and the second rotatable part (2, 3) to be easily dissembled.
