How to attach a potentiometer to a servo motor shaft

couka:
birddseedd, when will you stop opening threads in the forum before you have figured out what you want?

You want to control a valve both by hand and by a motor, right?

You didn't even use the word "valve" before your FIFTH post and another TEN answers from users that spent their time trying to help you.

Thats because im not controlling the valve itaelf but the handle bars their attached to.
