The problem with most hackers when they take the club back is the tension in the hands and shoulders. As one famous old pro said, "Your biggest enemies on the golf course are Tension and Anxiety."
You have to take the club back with your hands, since they are the only things attached to the club, but they must remain soft. If they tense up, you will jerk the club back and no good can come of that. And this softness must reach higher than your hands; it must go all the way to your shoulders. Only then can you really feel the power of a good golf swing. It's not a violent act; it's an act of grace and purity.
God, I miss Payne Stewart. His swing was the perfect example.
