A multi-directional coupling (10) consists of a tubular slipper (14) between a tubular member (12) and a race (16), there being engageable tubular friction surfaces (20, 36) on the slipper (14) and the race (16), and facing bearing surfaces (18, 22) on the tubular member (12) and the slipper (14) defining therebetween a channel (28) with pockets (28a) receiving roller members (30), there being an actuator (e.g. a tooth (30)) on the tubular member (12) engaging a recess (40) in the slipper (14), or a spigot or a pin(s) or a cam engageable with the slipper (14) to provide two, three or four different modes of operation (e.g. lock-up, freewheel in both directions, freewheel in one direction and/or the other).
