Bushing or not?

Ok, so I have another question...because this car was originally a p/s car and as mentioned above it was switched to manual, the original column coupler wouldn't engage with the new m/s box so my son used a coupler adapter that he was able to get from a member here, it works but the female splines on the adapter don't fit as tightly over the male splines on the box as we would think they would. Now the roll pin keeps it secure so it can't slip but it seems if it were tighter this would also help with the extra play. Has anyone experienced this? Is there a way to make that tolerance tighter? Thanks
