A spring clutch assembly with reduced radial bearing forces is described. The cl utch includes a shaft(43), at least first (49) and second (51) helically wound axially mounted springs for making frictional contact with the shaft (43), and engaging means (53,55) corresponding to each of the first (49) and second (51) springs for selectively applying a tig htening force to one end of each of the springs (49,51) in order to prevent rotation with respect to the shaft (43). Each of the engaging m eans (53,55) is radially and symmetrically disposed along the shaft (43) for eliminating radial bearing forces induced by the spring ends (57, 59, 61, 63).
