Ah lame, then they are shitty controllers.
Check the help to see if the effectors store there original position information otherwise you will need to create zeroed out curves for the actual rig.
It looks like the effectors just extend all the attirbutes you will need to one node rather than having it all scattered around.
To make controls that are zeored out, an easy way is to parent a circle to the effector, zero it out. Unparent it, duplicate it and parent the duplicate to the original and then delete the shape of the original. You have to make sure that the original and now parent curve transform is a child of the same parent as the effector.
Does that make any sense?
