A camshaft phase controlling device which has a quill shaft extending through a hollow camshaft and has one end of the quill shaft directly connected to the drive gear with the other end of the quill shaft formed with helical splines that are connected through a connector member to straight splines formed on the inside diameter of the hollow camshaft so that axial movement of a connector member located between the helical splines and the straight splines serves to rotate the camshaft a predetermined distance upon actuation of an electric stepper motor.
