A wind turbine () includes a first connecting structure () associated with the main shaft () fixed to a second connecting structure () of a rotor hub (). A plurality of blades () is coupled to the rotor hub (). A rotor locking disc () is carried on the main shaft (). The rotor locking disc () has a peripheral region and a plurality of rotor locking elements () in the peripheral region for receiving one or more rotor locking pins (). The first connecting structure () includes at least first and second sets of fastener holes ('). The first set of fastener holes () is located at a position radially inward of the rotor locking elements () and the second set of fastener holes (&#x2032;) is located between adjacent rotor locking elements (). The first and/or second set of fastener holes (&#x2032;) are used to receive fasteners () to secure the main shaft () to the rotor hub ().

A drive assembly for adjusting the pitch of a wind turbine blade comprises a stator having a cylindrical body and a drive member positioned at least partially within the cylindrical body and movable along an axis thereof. A mounting pin extends through an aperture in a wall of the cylindrical body for pivotally mounting the stator to a wind turbine structure.
