You can't turn a retrievulator because it is not from the redpower mod (even though it works with the redpower retriever). You have to remove it and place it again.

If you think that you placed it right but it appears to have moved by itself, be aware that the graphic for the retrievulator will show it facing upwards if someone else places it or after you leave the server and rejoin. However, it still works as it should.
