A mechanical coupling for use with a theatrical hoist including a shaft having a body portion and a head portion defining an external hexagonal end with flanked surfaces in a plane parallel to and radial with a centerline of the mechanical coupling, and a liner including an internal hexagonal end corresponding to the external hexagonal end of the shaft. The flanked surfaces of the external hexagonal end are configured to engage with the internal hexagonal end of the liner. The mechanical coupling enables transmission of a moment about an x-axis of the mechanical coupling and enables transmission of forces along a y-axis and a z-axis of the mechanical coupling. The mechanical coupling inhibits transmission of moments about the y-axis and the z-axis of the mechanical coupling and inhibits transmission of forces along the x-axis.

An armature is configured to come into contact with an actuator due to magnetic attraction force. An outer plate is fixed to an armature, the outer plate being located on an opposite side of the armature from the actuator, the outer plate being configured to rotate together with the armature. An inner hub is located between the armature and the outer plate to be movable in a direction along a rotation axis, the inner hub being fixed to a driven device. A rubber member is disposed between the inner hub and the outer plate to give an urging force to the inner hub and the outer plate in a direction away from each other. This electromagnetic clutch is configured such that the urging force of the rubber member non-linearly increases as the actuator and the armature approach each other due to the magnetic attraction force.
