The arrangement comprises a stop bar (1) formed from a cylindrical rod having a lengthwise slot therein. The stop bar (1) is secured to a fixed support within an actuator casing (7). A stop plate (15) is slidably secured in the slot and presents upper and lower stop edge portions (16, 17) for engagement with spaced limbs (23) of arm means for converting linear motion into angular motion. The position of the stop edge portions (16, 17) relative to the stop bar (1) is adjustable by means of replaceable shims (21) in the slot. |
