Abstract
A torque isolation device for a force-sensitive load having a safe force limit to be imposed thereon, configured to transmit upstream rotational force within the limit to the load and transmit any force in excess thereof to a load-isolated path, is comprised of a radially displaceable driving coupling which includes a cam member having a dwell and bi-directional, outwardly oriented camming surfaces bounding same receiving a cam follower secured to a pivotal drive arm radially extensible from a biased primary transmission position, wherein the cam follower is disposed within the dwell, to an extended overload position in engagement with mechanical ground wherein the cam follower is displaced along the camming surface.
