if the outside diameter (OD) of the shaft is the same size as the inner diameter (ID) of the sprocket, then there is no room for a collor or sleeve to fit in-between the two. The key fits into both and locks them from turning relative to each other. This is by far the best way to make the two mate together without slipping. if you need to make the sleeve, use metal on a drive spocket. the plastic will undergo to much force and will deform, fail, and slip. You can use a plastic sleeve if it is just a wheel to an axel or something.
good luck.
