The traditional method of control splits helm(rudder control) and lee helm(throttle control). Both are under the direct command of the conning officer, who is responsible for all orders to the helm and lee helm and setting and maintaining the course ordered by the officer of the deck. You need to be able to shift control of steering to aft steering in case of battle damage or steering failure on the bridge, and you need to be able to shift throttle control to the engine room for the same reason. The concept of splitting throttle control of engine 1 and engine 2 between stations as a part of the normal transfer of control is absurd and I have no idea why that was even a thing. I never heard of it when I worked on this system.
