Camshaft Rotor Coupling Orientation Help

In my haste to remove the couplings to replace the O ring, I forgot to mark the orientation to where the flat side of the coupling sits (the part the rotor fits on to) with regards to the camshaft. In this picture the couplings are lined up with the pin holes, but I don't know if this is the correct orientation, or if one or both of them should be rotated 180 degrees. Any direction/help greatly appreciated. Thanks in advance!
