Imo most of the power comes from the hips and shoulder turn and
the arm augments that, but mainly in respect to controlling the swing
path and plane.
Yes, I agree. Arm, especially forearm and hand, adds control and feel.
I use/think the word passive to indicate that the legs and core should be used more. It is more common to see players with too much arm and too little body. So, visualizing a passive arm with more emphasis on the leg and core helps these players. I also like to use "passive" about wrist and forearm movement just before, during and just after contact. I don't think you want to consciously monkey with your wrist/hand position other than to direct the ball where you want it to go.
But, all in all, OP is correct.
