A controller for controlling a system for changing the pitch of blades of a turbine engine propeller, the controller includes a fixed member (28) and a member (29) which is movable in translation along a longitudinal axis (X) relative to the fixed member (28), and an anti-rotation device (33) configured so as to prevent the rotation of the movable member (29) relative to the fixed member (28) about the axis (X). The anti-rotation device includes a longitudinal structural crossmember (35) which is mounted by a first and a second end (36, 37) on the fixed member, and support and guide unit (57) integrally in translation the movable member along the axis (X), the crossmember extending radially outside the movable member and the fixed member relative to a radial axis (Y) which is perpendicular to the axis (X) and being guided through the support and guide unit.
