Rotation is transmitted from shaft 8 through spline sleeve 3 to flange 1 which has clutch teeth a on its end face. By means of these teeth rotation is further transmitted to flange 2, having a series of holes around its circumference into which rubber bushings 6 have been inserted. Flange 4 is keyed on driven shaft 9 and has pins which enter rubber bushings 6. When the transmitted torque exceeds a preset value, flanges 1 and 2 are forced out of engagement so that flange 1 slides along the splines of sleeve 3 to the left, bending flexible disk 5. The maximum torque to be transmitted can be varied by adjusting circular nut 7 axially.
