You sound like you're confusing two different pieces.
The clutch cover finisher, is the Triumph logo on a black stick on plate you adhere with double sided tape, or RTV so you don't lose it. This is attached to the large round/sightly domed area of the main clutch cover for the left side of the motor.
There is also the clutch lifter kit, sold by
Brent at Newbonneville.com , that does use a tiny allen screw to hold the part in place on top of the little clutch activator mechanism where your clutch lever is attached.
