Abstract
A coupling mechanism is provided. The coupling mechanism includes a bushing assembly adapted to establish a coupling when rotated, a housing that is rotatable when torque is applied to the housing, a torque-limit member positioned between the housing and the bushing assembly such that when the torque-limit member is in a positive-lock state, the housing and bushing assembly rotate jointly upon the application of torque until a predefined torque level is attained. A compressible member is included that engages the torque-limit member to define through frictional resistance of moving parts and parts geometry a predefined torque level. The torque-limit member switches from the positive-lock state to a ratchet state when the predefined torque level is attained. When the torque-limit member is in the ratchet state, the housing rotates relative to the bushing assembly.
