Abstract: A blade pitch system for a wind turbine comprising a motor coupled to a central reduction gearing, wherein a rotatable output of the central reduction gearing is fixed to a mobile link that in use is joined to the blade and allows rotation of the blade around its longitudinal axis and a static part of the central reduction gearing or the motor is fixed to a static link that in use is joined to a wind turbine hub, wherein the system further comprises one or more flexible couplings to couple the central reduction gearing or the motor and the static or the mobile link such that torque about a blade longitudinal axis is transmitted between the blade and the reduction gearing while substantially limiting the transmission of other loads.
