Abstract: Precise angular relationship between release means and driven means is attained in a coil spring clutch by means of a spring-positioning ring which is permanently secured to the driven hub only after being rotated into desired position.

Abstract: An electromagnetically actuated clutch or the like having a helical spring disposed about the surface of a relatively rotatable drum, and an electromagnet with a fixed annular pole piece closely adjacent the free end coil of the spring. The spring is induced to grip the drum surface by the action of magnetic flux passing from the drum to the spring and thence directly to the polepiece.
