An angular actuating apparatus, intended to produce the limited rotation of a shaft coupled to a mechanical angular movement device, essentially characterized by comprising a hermetic body of elongated configuration, which houses a longitudinal axis supported by its ends on the faces body terminals, provided with needle caps to allow limited axial displacement of the shaft, which has at one end an extension associated with a plurality of springs in the form of an elastic crown, adjustable together by means of a terminal nut of the shaft, being surrounded by a second group of springs of the same shape, applied against the internal face of a bearing bearing and adjusted by means of a tubular head nut shaped in order to its external drive, said groups of springs operating as reaction elements in opposite directions in the axis direction.
