    I think I’d parent the icons to nulls located at the center of rotation. Then give each icon this counter-rotation expression:

    -parent.transform.rotation

    and something like this for scale:

    minSpeed = 0;
    maxSpeed = 700;
    minScale = [50,50];
    maxScale = [125,125];

    s = parent.transform.rotation.speed;
    linear(s,minSpeed,maxSpeed,maxScale,minScale)

    thank you so much! One more quick question. The rotation works perfectly. I just need
    to figure out the scale part now.

    I put this on my icon on the scale property/

    Yes, but you probably need to adjust the four values at the top to get it to work with your setup.
