Curb shut off valve broken?

I have the main shut off valve from the curb as pictured. I turned the rod just a bit clockwise and then it started to be loose. Did I break it? (I can move the rod slightly by touching it left or right) Or is this common? I left it alone thinking its damaged. Any info will be appreciated.

The rod you are looking at is attached to the curb valve with a brass carter pin or a brass nut and bolt. Turning it 1/2 half turn clockwise should turn the water off. You may want to try to remove as much dirt from around the rod as possible before trying to turn it.

Thanks John, it worked perfectly.
