A transmission arrangement for a wind turbine, comprising a gearbox having a drive output, an electrical generator having a drive input, a drive shaft extending between the drive output and drive input and which defines a rotational axis. In use, torque is transmitted from the drive output to the drive input through the drive shaft. The transmission arrangement further comprises a torque bypass arrangement associated with the drive shaft, wherein the torque bypass arrangement is configured such that torque is transmitted by the torque bypass arrangement, in use, from the drive output of the gearbox to the drive input to the generator upon mechanical failure of the drive shaft. A benefit of the transmission arrangement is that the torque bypass arrangement serves as a failsafe mechanism in the event that the drive shaft experiences a failure event which compromises its capacity to transmit torque between its input end and its output end.
