A radial ball torque limiter having a member with an annular wall defining a cavity with a plurality of rows of internal teeth extending circumferentially along the interior of the annular wall, an input shaft extending into the cavity, and one or more caged ball assemblies surrounding the input shaft with each having a circumferential row of balls loosely held by a generally annular cage to engage in ball-receiving recesses between adjacent teeth and the cage has a hub connected to the input shaft. A circular member positioned radially inward of the balls engages and yieldably holds the ball in the ball-receiving recesses during torque transmission from the input shaft to an output shaft and is yieldable upon the application of excessive torque to permit the balls to move inwardly and travel past the teeth to limit the value of the torque that is transmitted.
