Abstract

The invention relates to an actuator (10) for transmitting motion, comprising a cylindrical outer member (12), a wave generating means, (26, 30) and a flexible member (40), which is rotatably mounted on the wave generating means (26, 30) and co-operating helical means (16, 42) on the outer member (12), wherein the wave generating means (26, 30) is axially secured relative to the flexible member (40) and rotatable within the flexible member (40), thereby causing the co-operating helical means (16, 42) to move the flexible member (40) and thus said wave generating means (26, 30) axially relative to the outer member (12).
