Shaft couplings.-In a coupling for driving ignition magnetos in which automatic angular adjustment is obtained by centrifugal masses bearing on inclined surfaces on the driving and driven members, springs are provided in order to prevent ' hunting ' of the masses, and increased adjustment may be secured by the provision of one or more sets of centrifugal masses bearing on corresponding intermediate members mounted between the driving and driven elements. A pair of balls or rollers g1, g3 bears against projections b on a driving-disk (not shown) and against an intermediate member f, loose on the driver spindle d, a second pair of balls &c. g2, g4 being interposed between the member f and projections b1 on a disk e fixed on the spindle d. In order to keep the surfaces of the projections constantly bearing on the balls, springs i in compression are fitted between recesses h in the projections b, b'. In a modification, the intermediate member f and balls g2, g4 are omitted, the balls g1, g3 bearing directly against both projections b, b1. In another form, three sets of projections, balls, and springs, are used.
