Abstract
A drive lever comprising a first end for insertion into a slot of the hydraulic spool valve. The first end comprises at least two resilient members which resist radial compression (R, R) such that they exert a radially outward force (F, F) on one or more inner surfaces of the slot when inserted therein. This radially outward force (F, F) can account for any backlash that would otherwise be present between the drive lever and the slot due to manufacturing tolerances or wear.
