What Is This Called (71 Imperial 4Dr) (Rag Joint)

I have a bit too much play in my steering so I was going to adjust it and take some out. When I started checking the column I noticed excess movement towards the firewall side and saw this part seemed to have broke. I haven't pulled my tech manuals
yet to check but thought, maybe someone here can tell me what this part is called so I can check out the repair on it. Hopefully the picture (a 6 in 1 shot) will show so you can see it.

Thanks
