Abstract
A coupling assembly includes an annular housing, an inner member and a coupling pack including first and second sets of discs that alternate with each other and respectively have connections to the annular housing and the inner member. An actuator compresses the coupling pack to rotationally couple the annular housing and the inner member to each other about a central axis. One or more springs is received within the second set of discs between the actuator and the inner member for decompressing the coupling pack to rotationally decouple the annular housing and the inner member from each other about the central axis. A set of retainers in the form of retaining tabs hold the coupling pack, the actuator, the spring(s) and the inner member within the housing.
