Some engines come with a collet but most do not. The one in the picture I sent didn't come with one. (That model was my old Fantom, ran great for 8 gallons before giving up its compression). I don't get it, if you removed the 5mm collet from your old engine then it should just slide onto the 5mm shaft of the new engine.
If you look at the pictures from the Trinity site you will see that it is exactly the same one as on the Tower site. Why, because Tower uses the vendor's pictures and copy. Read the copy for both engines on Tower's site and you'll see that they are identical with the exception of one line of text describing Drake blueprinting the premium engine.
Besides that is a 5mm collet shown on the Trinity site. Also there is no mention of what comes included in the box on the Trinity site.
