Fan clutch bushing question

That brass bushing that goes in the fan clutch to help center it on the water pump snout is it supposed to be slightly longer than the hole in the clutch itself? I just noticed it while mocking up my aluminum pulleys. The bushing has a split down the length of it but with it sitting in the fan clutch it protrudes about 1/16” maybe a little less. Does it mash flush when tightened up? I had it bolted up before to the steel pulley and didnt notice any issue. When the clutch is tightened up does it mash the brass bushing in and that split there for a relief when it gets tightened up?
