  We use a covariant supermultiplet theory to determine the primary coupling
constant associated with several types of two-body meson decay. Despite the
diverse range of decays considered the primary coupling constant is
surprisingly uniform. We envisage the extension of the techniques to heavy
quark cases, including as preliminary examples the calculation of the $D^{*+}$
and $D^{*0}$ total decay widths with results $57.7 \pm 1.5$ KeV and $42.5 \pm
2.6$ KeV respectively, as well as some predictions about $D^*$ and $B^*$
radiative decays. (3 uuencoded Postscript Files are appended at the end of the
