An actuator assembly having a housing, at least one rotating gear member including a cam, and an actuator device operably connected to the rotating gear member, operably contained in the housing, for rotating the gear member. Also included is a bearing member operably associated with the cam such that when the actuator device is actuated for rotation of the gear member, the bearing member moves on the cam for providing relative motion between the bearing member and the rotating gear member. The actuator device is selected from a torque generating device or a device having linear movement.
