A rotor blade control device for a helicopter, comprising a swash-ring, said swash-ring comprising a non-rotating component of the swash-ring, coupled in a non-rotatable manner to the helicopter, a rotating component of the swash-ring, at least three actuators disposed around a rotor shaft axis of the helicopter, a coupling means between the actuators and the non-rotating component of the swash-ring. The coupling means can be adjusted in terms of its pitch, for changing the position of a swash-ring coupling point on the non-rotating component of the swash-ring along the rotor shaft axis by the actuator, by means of a control shaft, in order to adjust the rotor blades. The coupling means has a pushing member, in addition to at least one lever non-rotatably connected to the control shaft, which is connected at a first end to the lever in a rotational joint, such that it can pivot about a pivotal axis, and is coupled at a second end to the non-rotating component of the swash-ring at a swash-ring coupling point, in a ball joint.
