I was informed that pitching speed mostly (about 80%) comes from hip & shoulder separation.

http://www.youtube.com/watch?v=yEpdoAZiHWQ (3 components on Chapman's pitching velocity) (includes shoulder turn & torque). To be more specific, pitcher's front hip and his back shoulder separation creates massive torque.

From this perspective, will this technique work on increasing bat speed? I'm asking you this because I know that Ken Griffey Jr turn his front shoulder inward as he strides. I also know that Bonds has done similar thing as he made his stride. Is that where torque comes from in hitting? (I did see Griffey Jr vs. Bonds, lead arm, back arm videos)
