A torque limiting device for preventing the transmission of torque from a drive source to a torque responsive element when a predetermined torque limit has been reached. The device operates by transmitting torque between two axial members having a plurality of balls therebetween with the balls engaged within precisely shaped sockets contained within each axial member. As excess torque occurs, the plurality of balls cause one member to axially displace with respect to the other member and engage a plurality of discs which lock both members, thereby preventing torque transmission.
