This is how it should be,,the gas strut is only a damper to stop any bounce

Can not see how the spring tensioner has come off, some thing must have broken, get it fixed other wise it will wrap it self round and could cost you a lot of money , the easy way to replace new parts is to take the fan off, not expensive to have done if you can not do it your self about 1/2 hour job,hope this helps
