A fluid metering valve, for example as shown in FIG. 1, comprises a valve element moveable, axially and angularly, by a drive member, a sensor arranged to monitor the position occupied by a target carried by the drive member, and an adjustment arrangement whereby the axial position of the target can be adjusted relative to the drive member independently of the angular position of the target. A backlash free connection may be provided between the valve element and the drive member, the backlash free connection comprising a projection protruding laterally from one of the drive member and the valve element, the projection being received within a recess associated with the other of the drive member and the valve element, the dimensions of the projection and the recess being such that the projection engages the sides of the recess but is spaced from the base thereof, and biasing means urging the projection towards the base of the recess.
