  Al,
  Can you tell me how to properly tighten or what the torque should be on a good quality hose clamp or a constant torque clamp? This is a question I have never been able to find the answer. Thanks for your help.

No.  The problem is that you're using a metal strap to squeeze some rubber.  The torque is going to be more dependant on the temperature than anything else.  You torque it until the clamp visibly squeezes the hose. This make sure the clamp doesn't slip on the hose, and the combination won't be able to slip over the bead on the nipple.
