A wind turbine including a drive train. The drive train includes at least a rotor for transforming wind into rotation of a rotor hub, to provide a drive torque, a generator for transforming at least a part of the drive torque into electrical power, and at least one coupling for connecting a first drive train component to a second drive train component for transferring the drive torque between the components. The coupling includes a first coupling part with a first coupling area, the first coupling area being connected with a second coupling area of a second coupling part, whereby the drive torque is transferred from one of the areas to the other of the areas during operation of the coupling.
