Does an R11s shaft connector fit into a R11 head?

I believe it does apparently the adjustment is in the adaptor not the head so therefore an r11s green adaptor should give you 1.5* adjustment on your r11.
 
Hi it doesnt matter which adapter you get they will fit. However I was under the impression that the R11 Head would only be able to be moved 1 degree either side no matter what the adapter says. And the R11S will be 1.5 degrees.

I rang TM before I fitted the shafts I bought into the new R11S Driver

I think its almost for certain that an R11 shaft will fit into an R11s head, but the other way around is what I am trying to figure out
