A device for controlling a collective pitch and a cyclic pitch of rotor blades of a rotoreraft of a direct turbine driven type and. contra-rotating coaxial rotor type (DTDR) includes: a lower rotor and an upper rotor that are mounted concentrically on a shared rotor shaft; a first plate, that is not rotatable, fastened to a structure of the rotorcraft and connected to an actuator that communicates collective pitch and cyclic pitch controls to it, the first plate being mounted so as to be movable in translation along the shared rotor shaft and to oscillate relative to the shared rotor shaft, via a lower ball joint mechanism; and a second plate, that is rotatable, housed on the lower bail joint mechanism so as to be always parallel to the first plate, the second plate being driven in rotation by a member connecting it to the lower rotor.
