On my 1993 300SE the knob and handle are one piece and it is removed by pressing down (it is spring loaded) and turning a quarter of a turn in either a right hand or left hand direction. Sorry, I cannot remember which. Use caution if yours is this type as not keeping it inline when doing the removal or replacement, it is easy to tear off the lip holding the c clip which keeps the spring in place. The yoke is made of cheap potmetal and I tore off two (at about $30 each) when working on my shift console.
