An aircraft control surface deployment system 100 for an aircraft structure, for example a spoiler deployment system for an aircraft wing, comprises a cam body 300, an actuator 200 and a coupling mechanism 120. The actuator moves the cam body such that it raises and/or lowers the aircraft control surface. The actuator is connected to the cam body via the coupling mechanism 120. The coupling mechanism has a first portion 320 connected to the cam body and a second portion 220 connected to the actuator, configured such that the coupling mechanism allows some free relative movement and rotation of the first and second portions. Loads transverse to the axis of movement of the actuator, resulting from relative movement of the cam body, are not transferred to the actuator. The coupling mechanism may be provided as a ball joint comprising a ball portion 320 and cup portion 220.
