Hi Chief. No, mods from your weapon do not enhance your shield attack strengths. Only (as of now of course, who knows what the future holds) your guardian skills may enhance your shield's attack strength (ie, Shield Bash, Shield Turn, Shield Master). And of course it doesn't work the other way around iether. For example, if your shield has shield penetration attribute or addition stun attack strength, that only applies to shield skill groups, and not for your weapon (ie, sword, mace, guns, etc).
Btw, have you tried using a spectral splash shield + shield turn? When it phases, it does an insanely amount of damage. Perhaps it's bugged...against NM Shulgoth, once it gets phased he dies within seconds.
