Abstract: A ball-detent torque-limiting assembly has breakout means for maintaining an axial separation distance between opposing pocketed surfaces of the assembly once the primary balls of the assembly have rolled out of their pockets, wherein the axial separation distance maintained by the breakout means is at least as great as the diameter of the balls. The breakout means may include a plurality of secondary balls deployed in a breakout event. The breakout means assumes the axially directed spring load that urges the opposing pocketed surfaces together, thereby preventing the primary balls from entering and exiting the pockets in quick and violent succession following breakout and avoiding damage to the torque-limiting assembly. The torque-limiting assembly is resettable by counter-rotation following a breakout event.
