1. A steering gear assembly for a vehicle, the steering gear assembly comprising:
a first rotatable input shaft;
a rotatable valve member coupled with the first rotatable input shaft, wherein the rotatable valve member is configured to control flow of hydraulic fluid from a hydraulic fluid inlet to a first downstream passage and a second downstream passage;
a torsion tube configured to apply a rotational restoring force to the rotatable valve member and the first rotatable input shaft;
a second rotatable input shaft; and
a transfer shaft extending within an interior of the torsion tube, coupled to the rotatable valve member and being integrally formed with the second rotatable input shaft, such that the rotatable valve member is configured to rotate upon receipt of torque from either of the first rotatable input shaft or the second rotatable input shaft.
