First, insert the black plastic control valve all the way into the hole. Make sure that the rounded face with the cut in it is facing toward the tall part of the chamber/hole where you inserted the valve. Try to line up the dial with where the threads would enter the cut in the valve. Hint: the hole in the center of the dial will go over the tall part of the chamber wall. Once you believe you have it aligned correctly, replace the plastic body cover and keep the dial out of the body cover. Just put in the screw on the side the dial is on, so if it is not aligned properly, you can remove the cover more quickly. Once you have the body screwed down, screw the dial into the hole and it should align easily with the valve in the hole. If not, remove the body cover, and try to realign the valve again. Repeat until you get the dial to screw in easliy.
I just did this today because I had to fix a customer's unit. It took me about 20 minutes or so to figure it out, but I finally got it. I was hoping your question had an answer to it when I got on here, but at least I got it figured out anyway. Hope this helps! That is if you still have this unit...
