An actuator arm lock (28) suitable for use with an actuator (10) which has an actuator arm (14) and an actuator body (12) is disclosed. The actuator arm lock (28) comprises a lock ring (26) suitable for clamping around an actuator arm (14). The lock ring (26) comprises a circumferentially extending element (30) and a locking element (32). The circumferentially extending element (30) comprises first and second element ends (34, 36) and an inner surface (74) which faces towards the actuator arm (14) when the actuator arm lock (28) is in use, and the circumferentially extending element (30) is configured to partially extend around the actuator arm (14). The locking element (32) comprises first and second locking ends (44, 46) and is configured to extend at least between the first and second element ends (34, 36) of the circumferentially extending element (30). The first locking end (44) of the locking element (32) is engaged with or engageable with the first element end (34) of the circumferentially extending element (30), and the locking element (32) is engaged with or engageable with the second element end (36) of the circumferentially extending element (30). The locking element (32) may be reversibly reconfigured between a locked configuration in which the actuator arm lock (28) clamps onto the actuator arm (14), and an unlocked configuration in which the actuator arm lock (28) is loose on the actuator arm (14).
