How to remove PS box

I guess I don't understand why folks are showing you how to disassemble the coupler when all you want to do is take the whole column out... the coupler stays attached to the steering column.
I have to admit that any time I have dealt with steering issues its been because the steering was sloppy and I determined the issue was inside the coupler so of course my answers draw upon my experience. Just IF advise not intended to be "be all end all" A-Z how to.
