A latching failure detection mechanism for a rotary drive system is disclosed. A pair of mating clutch jaws are provided, with each jaw torsionally connected to a respective one of a pair of input members, such as the ends of a closed loop drive line. The jaws are relatively axially and rotatably movable. The jaws are movable from a first, inoperative position wherein the jaws simply rotate with the input members and a second, latching position wherein the jaws relatively rotatably move to a latched condition in response to relative failure rotation of the input members, thereby providing a torque path through the jaws in the latching position. An indicator is provided operatively associated with a movable one of the clutch jaws for providing a positive indication that the jaws have moved to the latching position.
