An actuator apparatus comprising an actuator member (36), an actuated element (30, 34) movable by actuation of said actuator member (36), and a marker device (50) including a marker (64) the position of which can be sensed in use by sensor means (40), said marker device (50) being secured to said actuator member (36) such that deformation of the actuator member (36) during actuation to move said element (30, 34) causes an adjustment to the change in position of the marker (64). <IMAGE> <IMAGE> |
