You don't really need to use the Torx side to get the bolt loose or off. The bolt is a centering bolt from the manufacturer and has an oval center to fit in the oval section used for the correction bolts. It will hold itself when you turn the other side. All you basically need is a 22mm wrench to loosen the bolt.
I'm not sure what the Torx size is, but its probably 45 or 50.
